MACHlN E FOR GAGING THE THI'CKNESSIOFMATEIRIALY. A

To altwlwm it may concern:

Be it'known that we, lllrNA C. WELLs and ALFRED WELLS, citizens of the United States,

residing at- New York, 1n the boroug'h of Manhattan and State of New..-York, have jointly invented certain new and useful 1m provements in Machines for Gaging the Thickness of Material, of which thefollowingis a specification.

Our invention relates to means for gaging and indicating the thickness of-sheet matefor regulating the stroke of the rod for operating said gage.

In the accompanying drawings, Figure 1 is a plan-view of part of one of the rolls of the stack, showing our invention in position with relation thereto. Fig.2 is an end view of part of the stack, showing the gage attachment in side elevation, with its support in section. Fig. 3 is a detail View illustrating the swinging lever in whichthe rollers hereinafter' described are journaled. Fig. 4; is a rear view with the closure removed of one of the many forms of gage that, may be employedand also illustrates in section the pivoted roller-carrying lever; Fig. 5 is a front view'of part of the stack, showing by dot-anddash and dotted lines different ways in which the attachment may be adj ustably supported with relation to the rolls. tudi'nal section ofthe adjusta le devices at the lower extremity of the gageoperating rod. Fig. 7 is a section on line 7 7 of Fig. 1,

and Figs. 8 and 9 are views of afurther modification.

Like numerals throughout the several views.

Referring to the drawings, the numeral 1 indicates the housings of a stack of rolls; 2,

said rolls, and 3 thejgurnal-boxes thereof.-

Specification of Letters Patent. Application filed Jul y l' '7. 1906. Serial ilo 326,660.

Fi 6 is a long1- designate similar parts Patented J an. 22, 1907.

I Projectin from one of the journal-boxes is a d at right angles to said bar is a stud bar 4, an

5, which although shown integral with the bar may ,be detachable, if desired; This stud washer 7 (held to its work'by a'nutS) a-split drical rod 11 carrying the support (designated in a general way by 12) of the gage or indicator 13, the suplport having a split hub 12 adjustable aroun thereto by a bolt 12 Support 12 is of pecul iar form and comprises a U-shaped body arm 1 5 depending therefrom. Said arm 15 has a comparatively long bearing 16 to receive a shaft 17, on the end of which are pivoted the or rod 19 in the endof the frame opposite the pivotal point is a roller 20, and rising from the bearing of .said roller arearms 21, connected by a cross-bar 22, Figs. 4 and 1; said cross-bar having a bifurcated boss 23, in

- which is mounted an antifriction-roller 24.

Depending from the frame of the gage is a tubular extension 25, and integral with the top thereof is a tubular boss 26. This gage dial 27 and usual gearing 28 for actuating the pointers of said gage. These matters constitute no part of the invention and are fully to which reference maybe had. 4 A rod 28 passes through the frame of the gage and carries a rack 29, by which the to receive an externallythreaded split -nut knurled periphery and being clamped in place by a nut 36, engaging its split portion, as shown in Fig. 6.

the arm 15 of support 12, and to the head 21 sleeve 9, clamped or released by a'lever-' screw 10.. This sleeve is rigid with. a cylin-' the roll 11 and secured having an arm 14 rising therefrom and an pointer-actuating gearing is operated, and surround said rod and 34, said nut having a head 35, provided with a A-slotted guide-bracket 37 depends from is reduced and threaded at its outer end at 6, and upon it is sleevedbetween the bar-and a v arms ofa frame 18. Rotating on the shaft is shown of the usual Waltham kind and a disclosed in-t'he patent granted H. H. Burton and J. LeBurton June 20, 1905, No. 793,027,

knurled stop 32 of the rod. At its lower extremity the rod'28 is threaded at 33, Fig. 6,.

offrame 18 is secured a screw or pin 38,

which prevents the frame 18 and its rollers and 24 from dropping beyond a certain point when the attachment is swung away made for a slight adjustment longitudinally of the rolls of the stack of the carrier 12 upon the rod 11 when bolt 12 is released.

From what has been stated it will be seen that the movement of the rack-carrying rod 28 can be regulated with nicety and precision by the devices described and located at the upper and lower extremities of said rod and the head 35 of the nut 34 serving as adjustable abutment to receive the bearing thrust of the roller 24, carried by the swingin frame 18.

Fig. 5 part of the stack is shown, and two diflerent ways of supporting the carrier 12 are delineated. In one of these ways a rod 39 is clamped in boxes 40, secured to the housings of the stack, said rod being illustrated partially in full and partially in dotted lines and the carrier being adjustable either longitudinally of or around the rod. In the same figure a stand 41 is shown by dot-anddash lines, and the carrier 12 may be adjusted thereon as desired.

In Figs. 8 and 9 brackets 42 (one of which is shown) are bolted to the bushings, and in- ,dicating mechanism of the character before described will be, carried by each bracket, while instead of gaging from one of the work ing rolls of the mill a measurement of the finished product 43 is made, said product passing from the stack to and between the roll 20 and a roll 44, journaled in bearings '45 of each bracket 42. A rod 46, on which to secure the indicating mechanism, is fastened in tubular bosses 46 of said brackets 42' After leaving the rolls 20 and 44 the sheet material passes beneath a roller 47 to a reel or other device in the usual manner.

v In operation all the forms of the attachment operate in a similar way, and one or any number of said attachments may be employed. If employed with a stack of papercalendar' rolls, the roller 20 in engagement with a st d i-roll will rise and fall in accordance with the thickness of the paper and through the connections described will cause the gage to indicate any variations inthe sheet I differing from standard, while in Fig. 8 the" same result will be obtained in connection .v 'ith the finished product.

In old forms of construction there is more or less chattering of the age-operating rod 28, thereby somewhat afl ecting-the accuracy of the gage; but by ivoting theframe 18 in the manner described and employing the roller 24, beari against the abutment 35, this trouble wil be entirely overcome.

While primarily designed for use with paper-calendering rolls, the invention is not restricted to any special machine nor to any specific art.

Changes may be made in the constructional details of the invention, which is not limited to the precise devices shown and described.

Having, thus described our'invention, what we claim is- 1. The combination, with a pivoted frame having an angular extension, of a roller journaled in said frame; an antifriction device carried by the angular extension of the frame at a point opposite the roller; an indicator; and means actuated by said antifriction device for operating said indicator.

2. The combination, with a support having means, whereby said support may be turned in an arcuate path, and then secured in position, of an indicator carried by the support mechanism for actuating the pointers of the indicator; a rod for operating said mechanism a swinging frame; a roller journaled in said frame; and an antifriction device carried by the swinging frame and adapted to actuate the rod.

3. The combination, with a support, and with an indicator carried by said support, of gearing for actuating the pointers of the indicator; a movable rod; a rack carried by'said rod, and engaging with anlelement of said gearing; a frame pivoted to the support; a roller journaled in said frame, andadapted to bear against the material to be gaged; and means carried by said frame, and engaging the rod to actuate the same when variations in the thickness of the material undergoing operation occur.

4.
